pip install jedi Common errors
error ModuleNotFoundError: No module named 'jedi' ↓
cause The 'jedi' package is not installed in the Python environment being used, or the Python environment where it is installed is not correctly configured in the IDE/editor.
fix
Ensure 'jedi' is installed in your active Python environment:
pip install jedi or python -m pip install jedi. error AttributeError: module 'jedi' has no attribute 'Script' ↓
cause This typically occurs when an outdated or incompatible version of 'jedi' is installed, or when there's a conflict in the Python environment leading to the wrong 'jedi' module being loaded. The `Script` class might have moved or been removed in a newer major version, or the installed `jedi` is too old for the code trying to use `Script`.
fix
Upgrade 'jedi' to the latest version:
pip install --upgrade jedi. If the issue persists, ensure no conflicting 'jedi' installations exist and try reinstalling it: pip uninstall jedi && pip install jedi. error ImportError: cannot import name 'traverse_parents' ↓
cause This error points to an internal inconsistency or version mismatch within the 'jedi' library or its dependencies, often due to a partial or corrupted installation, or an incompatibility with the Python version being used.
fix
Reinstall 'jedi' to ensure all its components are consistent:
pip uninstall jedi && pip install jedi. If using a specific editor plugin (like jedi-vim), ensure it's compatible with your installed Python and jedi versions. error AttributeError: module 'typing' has no attribute '_SpecialForm' ↓
cause This error often arises from a compatibility issue between the 'jedi' library (or its components like 'jedi-language-server') and the `typing` module, particularly with older Python versions or specific setups where `typing` might be backported or have an unexpected structure.
fix
Update
jedi and any related language server components to their latest versions: pip install --upgrade jedi jedi-language-server. Consider ensuring your Python environment is up-to-date, especially if you are using an older Python 3.x version. Warnings
breaking Deprecation of Python 2 support in version 0.16.0 ↓
fix Upgrade to Python 3.6 or later.
gotcha Use of deprecated 'completions' method in version 0.16.0 ↓
fix Use the 'complete' method instead.
breaking Unspecified failure during library load process. ↓
fix Review the full test logs for detailed error messages or stack traces leading to the 'load' event to identify the root cause.
